Spread some ice melt (from your local hardware store) on on the snow. ( If this is snow is on or near grass/plants, the salt can damage the plants and prevent them from growing in warm months which can require replacing the soil. There is a non salt based ice melt that is also available.
Magnesium Chloride ice melt is supposedly safe for concrete and plants, but using it on fresh concrete with less than a year of cure time and freeze thaw cycles may still cause cracking/chipping.
Calcium chloride has a fast reaction time but will definitely harm plants and concrete.
If you are not concerned with grass damage later, this would melt it faster. Just be sure to scrape off the excess salt to try and protect the concrete/cement/brick to protect it if using Calcium chloride.
Sand/gravel or cat litter can provide traction (better for ice than snow), but it won't melt the snow.
Hopefully this helps.
